Patent GB-1419906-A (GB)
Title: Semiconductor devices manufacture
IPC: H01L23/522
Filed: 1974-02-04
Abstract: 1419906 Integrated circuit RAYTHEON CO 4 Feb 1974 [12 Feb 1973] 4995/74 Heading H1K In a semiconductor integrated circuit having a first pattern of conductors formed on a first insulator supported on the semiconductor body and contacting active elements through apertures in the insulator, the conductors being formed by depositing conductive material over the first insulator and removing selected regions of this material by sputter etching through a mask which is converted by the sputter etching to a compound which is removed by the sputter etching at a lower rate than the regions of the conductive material, a layer of titanium dioxide is formed over the first conductors by sputter deposition of titanium in an oxidizing atmosphere and a second insulator layer, e.g. of SiO 2 , is formed thereover. The arrangement provides improved bonding between the insulating layers and the conductive pattern and further conductive patterns which are preferably provided over the second insulator. The first conductive pattern comprises a first layer of titanium, a second layer a platinum and a third layer of gold formed by vacuum deposition or sputtering. A layer of titanium or other refractory metal is deposited over the gold and selectively removed by chemical etching through a photoresist mask to form a mask for forming the first conductive pattern. Thus portions of the multilayer conductor are selectively removed by sputter etching in an argon-oxygen atmosphere. The titanium mask and the lower layer of titanium in the multilayer conductor are oxidized in the sputter atmosphere, this titanium dioxide only being slowly removed by the sputter etching which is thus stopped at this stage, the remaining titanium dioxide being removed by chemical etching. A layer of titanium dioxide 100Š thick is then formed over all the exposed surface by sputter deposition of titanium in an oxidizing atmosphere. The second insulator, SiO 2 , is then formed over this TiO 2  layer by chemical vapour or sputter deposition. Subsequent patterns of conductors with interconnections to other patterns may be formed as before over these two insulating layers.

Title: Improvements in or relating to machines organized for use in performing cutting out operations on work-pieces
IPC: C14B5/00
Filed: 1939-02-17
Abstract: 525,288. Cutting-out presses. BRITISH UNITED SHOE MACHINERY CO., Ltd., and BOOTHROYD, H. Feb. 17, 1939, No. 5235. [Class 31 (i)] A machine for cutting out shoe parts &c. comprises a vertically reciprocating plunger carrying the cutter, hand-operated means for moving the plunger into contact with a work piece, and power-operated means, subsequently operable, to force the cutter through the work piece, adjustable means being provided for ensuring that cutters of varying heights will have their cutting edges at the same level at 'the end of a cutting stroke, and means for preventing assembly of a cutter on the plunger unless the adjustable means has been adjusted so that a cutter of maximum height could be assembled. The machine comprises a plunger 19 to which the cutter 33 is attached and which is initially depressed by the operation of a treadle-actuated lever 25 into contact with the work piece supported on the bed 11 ; the lever 25 engages pins 23 provided on the plunger. Another treadle is then actuated to operate a lever 83, an upwardly extending arm of which is in interlocking engagement with the lever 25 and a downwardly extending arm fitted with a wedge 81 which engages a spring- influenced bolt 77 to couple a driving pulley with a shaft 5. A block 17 is thus depressed by means of an eccentric 75, link 9 and lever 15 to operate the plunger 19. The bolt 77 can be withdrawn after a half rotation of the shaft 5 to maintain the pressure by a wedge 99 carried by a spring-influenced arm 95 ; the bolt is reengaged when the lever 83 rises by the engagement of a rod 101 thereon with the lever 95. To allow for varying heights of cutters 33 the block 17 is fitted with a wedge-shaped head 35 adjusted by a screw 37. The knives are carried on a base plate 49 fitted with a pair of studs 51 fitting in sockets in the plunger 19 and between which is a spring-returned locking stem 55 engaging grooves in the studs; on moving the stem inwards a portion 57 of reduced diameter allows the studs to be withdrawn. To prevent the actuation of the locking stem 55 unless the plunger 19 has been adjusted to take a knife of maximum height, the stem passes through a keyhole slot in a plate 63 having notches engaged by ledges 61 on the wedge member 35 ; the stem 55 can pass through the slot only when the parts have been correctly adjusted. The lever 25 may engage the pins 23, 19 through a spring-pressed plunger to remind the operator to depress the lever 25 to free it from the lever 83. A stop 105 may prevent the operation of the levers 83 and 25.

Abstract: 764,167. Drawing instruments. AKTIEBOLAGET SUPERMARIN. Feb. 22, 1955 [Feb. 24, 19,54], No. 5327/55. Class 97(3) In drawing apparatus, a protractor or the like is connected by a universal joint to one end of an extensible rod consisting of two members displaceable longitudinally relative to each other but incapable of relative rotation, the other end of the rod being connected by a universal joint to means for securing the apparatus above a map, chart table, drawing board or the like. As shown in Fig. 1, a protractor 3 made of transparent material rests on a map 2 carried by a table 1. A sleeve 4 on the protractor receives a member 7 of a universal joint A, which may be clamped by means of a knob 9. The joint A connects the member 7 to a rod 11 a slidable telescopically within a sleeve 12, but having a groove 13 therein engaging a projection (not shown) within the sleeve 12 to prevent rotation between the parts 11, 12. Sleeve 12 is connected through a universal joint C to a member 8 fitting into a socket 5 fixed to a part 6, which may be part of the ceiling or wall of the room, or a support arm. Member 8 is rotatable within the sleeve 5, and may be clamped in adjusted position by a screw 10. The protractor 3 has graduations round its edges indicating the angle at which it may be set at any required angle to the map. Screw 9 or screw 10 is then tightened up, and the protractor may then be move'd at a constant angle over the map 2. In a modification, the outer sleeve 12 is of rectangular cross section, and is narrowed at one end to receive a thin rod which replaces the rod 11. The thin rod carries at its free end a rectangular block which slides in guides within the rectangular tube. The sleeve 7 may contain an electric lamp, which illuminates the protractor and a small area of the surrounding chart. The graduations will then become visible as bright lines. Sleeve 7 may also carry an index co-operating with the scale inscribed on the top part of the protractor. The protractor may then be set at an angle to the lines of latitude or longitude corresponding to the magnetic deviation, and courses may thereafter be set by means of the index and scale. A telescope or the like may be connected to the member 8, so that its direction is indicated by the protractor 3, which is preferably shaped as a right angle triangle, but may also be square. The apparatus may also be used for drawing, particularly on horizontal boards.

Title: Machine for pressing dowels into a work piece
IPC: B27F4/00
Filed: 1965-02-08
Abstract: 1,046,372. Dowelling machines. H. NOTTMAYER and J. NOTTMEYER. Feb. 8, 1965 [Feb. 20, 1964], No. 5381/65. Heading F2H. In a machine for pressing dowels into bored holes in a workpiece 13 the dowels are brought individually and sequentially into the pressing plane and are pressed into corresponding holes of the workpiece by a punch 1 having its free end shaped as an injection nozzle 5. The punch 1 has an axial conduit connected to a supply of glue 3, the punch being movable in a longitudinal passage in a chamber 16 of the machine. The nozzle 5 is controlled by a longitudinally slidable needle 9 having the front end shaped as a cone valve 10 which in the starting position of the machine, closes the axial bore 6 of the nozzle. The needle is connected at its rear end to a control lever 11 swingable around a horizontal pivot 11a which on coming to rest at a stationary adjustable stop 12, pulls back the needle 9 thus clearing the nozzle bore 6 on the pressing punch having completely penetrated the bore hole of the workpiece. The machine operates in a two-stroke cycle so that at the end of the first stroke the pressing punch 1 has moved back to its starting position and the control lever 11 has pushed needle 9 forwards and the nozzle 5 is closed. On the second stroke a dowel 14 enters from the conveyer line 15 into the feeding chamber 16 and at the same time the arm 23 is swung downwards and presses a vertically movable pin 21 against the dowel. The punch 1 presses the dowel through the discharge opening 19 into the bore hole in the workpiece but makes a shorter stroke than during the injection processes so that the control lever 11 does not come to rest at the stop 12 and the injection nozzle is kept closed.

Title: Improvements relating to wide band aerials
IPC: H01Q9/14
Filed: 1958-02-19
Abstract: 887,555. Aerials. TELEFUNKEN G.m.b.H. Feb. 19, 1958 [Feb. 19, 1957], No. 5473/58. Class 40(7). A wide-band aerial comprises at least two coplanar aerial elements, each element being divided into at least two sections connected by an impedance. The elements are spaced apart in the direction of propagation or reception, and the impedances are such that at low frequency the aerial elements are excited predominantly by standing waves, while at high frequency they are excited predominantly by travelling waves. In a first embodiment, Fig. 1, the elements 1, 2 and 7, 8 are divided by the impedance units 5, 11. The aerial is directive in the direction of the arrow but may be designed to become substantially omnidirectional at certain frequencies. In other embodiments the aerial is made symmetrical, as in Fig. 2, to form a multiple V arrangement. The angle between the pair of elements forming a V may differ from that between the neighbouring elements, Figs. 4a, 4b, 8a, 8b (all not shown). The electrical length of the conductors 13, 14 between the elements may be modified, for example by the insertion of an inductance or the embedding of the conductors in a dielectric. The feeder 15, 16 to the radio apparatus may be connected to an aerial element, or pair of elements as in Figs. 1 and 2, or to a point on the feeder 13, 14. This point may be variable. The aerials may be stacked, the planes in which component aerials lie being parallel. The sections of each aerial element need not be collinear, and an aerial of this type may be mounted as in Fig. 9. In this instance, the angles that the various sections make with the horizontal is varied by adjustment of the -tension in ropes 60, 61, or by loading the elements at suitable points along them. Specification 629,986 is referred to.

Title: Improvements in or relating to optically indicating measuring instruments
Filed: 1938-02-21
Abstract: 511,541. Indicating-apparatus. SIEMENS & HALSKE AKT.-GES. Feb. 21. 1938, No. 5475. Convention date, Feb. 22, 1937., [Class 106 (iv)] In an indicating instrument, light is reflected from a mirror operated by a measuring mechanism and passes through a mirror system to a scale, several mirror systems being provided and becoming operative in turn as the measuring mechanism mirror is deflected, the systems being so arranged that the light beam reaches the scale only during predetermined parts of the deflection of the measuring-mechanism, the said beam moving in the same direction across the scale during a complete deflection of the measuring mechanism. Light from a source 1 passes through a diaphragm and a lens 4 to a mirror secured to the measuring-mechanism shaft 2. When this shaft is turned anticlockwise into the zero position the beam is reflected by the mirror system 5, 6 to the zero 0 of, the scale. As the shaft 2 turns clockwise, the beam leaves the mirror 5 and, on account of the arrangement of the mirror on the shaft 2, does not impinge on the scale. When the shaft 2 has turned to the angular position a1, the beam is reflected by the mirror system 5<SP>1</SP>, 6<SP>1</SP> on to the scale at A1 and while the shaft moves clockwise from a1 to a the beam moves from A1 to A. A magnified indication is thus given in the zero area and over the deflection a-a1, no indication being given over the rest of the range. The mirrors are, so arranged that the rays reaching the positions O, A1, A originate from a common point at the centre of curvature of the scale. More than two sets of mirrors may be provided to give more than two ranges of indication. One stationary mirror only may. be nsed in, each range.

Filed: 1962-02-13
Abstract: Anthraquinone derivatives of the formula <FORM:0931316/IV(a)/1> in which R is an alkyl group and the benzene residue A may be substituted, e.g. by halogen, are prepared by an additive reaction between a 1,4-naphthoquinone and a 5,5-dialkoxy-1,2,3,4-tetrachlorocyclopentadiene of the formula <FORM:0931316/IV(a)/2> The latter is obtainable by treating hexachlorocyclopentadiene with an alcoholic solution of potassium hydroxide.  The reaction between the naphthoquinone and the tetrachlorocyclopentadiene derivative is preferably effected at above 100 DEG C. in an inert solvent, e.g. nitrobenzene, di- or tri-chlorobenzene or water. The products may be treated with sulphuric acid to yield tetrachlorodihydroanthraquinones, from which tettrachloroanthraquinones are obtainable by treatment with atmospheric oxygen or hydrogen peroxide.  Examples are given of the reaction of 1,4-naphthoquinone and 5,5-dimethoxy-1,2,3,4-tetrachlorocyclopentadiene.  The use of the corresponding 5,5-diethoxy, 5,5-dipropoxy and 5,5-diisobutoxy compounds is mentioned.

Title: Improvements in or relating to apparatus for issuing gummed strip paper, suitable for use for packing and like purposes
IPC: B65H37/00
Filed: 1932-02-24
Abstract: 392,313. Printing-apparatus. LEVANE, R., 5, Garrick Villas, Hampton, Middlesex. Feb. 24, 1932, No. 5573. [Class 100 (ii).] Rotary machines.-In an apparatus for delivering gummed strip paper comprising a paper roll mechanism B, a printing mechanism C, and a moistening or gumming device D, all carried by a single casing A, the printing mechanism comprises one or more type-wheels C2, one or more inking rollers C12, and one or more adjustable spring blades C19 which press the paper against the type-wheels so that as the paper is pulled the type-wheels are rotated. Preferably, each blade C19, when more than one is provided, is independently adjustable in relation to its type-wheel, and at the same time all the blades C19 can be moved as a whole away from or towards the type-wheels, thereby allowing unprinted paper to be withdrawn when required. The type-wheels are freely mounted on a spindle C1 and are spaced apart by separating plates. Four distance rods C5 .. C8 are mounted parallel to the spindle C1. The rod 65 carries a number of collars C10 carrying bolts C11 to which are attached springs C18 acting on the inking-rollers as described below. The distance rod C6 supports the inking-rollers C12. Each inking-roller is freely mounted on a separate stub shaft C13, Fig. 4, each held at one end in a carrier plate C14 moveable about the rod C6, the rollers being positioned by collars C15 on the rod C6. Each carrier plate and roller can thus be swung about the rod C6, so that the rollers can be changed individually. Each plate C14 is bent over at its upper end, and is provided at that end with an aperture C17 to which is attached a spring C18 to hold the roller against the type-wheel, as described above. The tension of the springs C18 can be adjusted by altering the position of the collars C10 by means of the bolts C11. The distance rod C7 carries the blades C19, and the distance rod C8 carries adjusting means for the blades. These adjusting means comprise eccentric collars C20 on which the free ends of the blades C19 lie and which are clamped on the rod C8 by bolts C21. One blade C19 and one collar C20 are provided for each type-wheel so that the action of each wheel is separately adjustable. To permit the blades C19 to be moved as a whole away from or towards the type-wheels, the rod C8 is mounted in slots up and down which can be moved by cams C22, Fig. 6, fixed on a shaft C23 and acting on circular nuts C9 on the rod C8. The shaft 23 is operated by a handle C25, which has two extreme positions attained with the aid of a spring ball C26 cooperating with appropriate depressions on the outer face of the casing. One wall of the casing is hinged, to give access to the mechanism. The inking-rollers may be replaced by carbon rollers or equivalent mechanism, and the typewheels may be mounted similiarly to the inking rollers. The apparatus may be combined with known means for causing a predetermined length of paper to be withdrawn.

IPC: H01J9/22
Filed: 1945-03-06
Abstract: 591,506. Luminescent materials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 6, 1945; No. 5619. Convention date, Feb. 27, 1942. [Class 39 (i)] A fluorescent screen is made by introducing a layer 3 of clear binder solution to the cathoderay tube 1, spraying an aqueous suspension of a phosphor evenly on the surface of this solution and allowing all or part of the phosphor to settle on the glass, introducing a second solution which precipitates the solution of the first, allowing the precipitate to settle and removing the liquid by siphoning or careful pouring. The solution and suspension are introduced through an elongated funnel with a rose 4, 3 or 4 ins. above the surface, the funnel being rapidly rotated while the suspension is passing through the rose, to ensure even distribution. The dimensions of a satisfactory, funnel are given, including the head of liquid necessary to prevent dripping. After the precipitate has settled a second layer of phosphor may be allowed to settle as the first and the thickness of the intermediate binder layer can be such that it acts as an electron barrier layer. The suggested solutions are a metal silicate e.g. potassium silicate and an alum such as potassium aluminium sulphate, potassium aluminium silicate being precipitated. The phosphor may alternatively be introduced as a suspension in the first solution. Strength of the solutions are given.
